Android practical fundamental question and answer

1. What is the Android SDK?
   For the development of any mobile application in Android Studio we need some tools, and this requirement is satisfied by Android SDK, which is a set of tools that are used for developing or writing apps. It’s a GUI, which emulates the Android environment. The Android Emulator acts like an actual mobile device on which the developers write their code and then debug/test the same code to check if anything is wrong or debug on the mobile.
2. What is Context in Android?
   The Android Context is a handle to the android system; it provides services like resolving resources, obtaining access to databases and preferences, and so on. An Android app has activities. Context is like a handle to the environment your application is currently running in. There are two types of context using on Android:
   • Application Context
   • Activity Context
3. What is Activity in Android?
   The Activity performs actions on the screen. If you want to do any operations, we can do it with activity. We can create multiple activities as per our requirement on Android Studio for our application. In Activity, we can add UI part and logical coding as per our application requirement.
4. What is the APK format?
   The APK format of the application bundle is in one file. The Android packaging key is compressed with classes, user interface, supportive assets, and manifest. All files are compressed to a single file is called APK.
5. What is build type in Gradle? How to use them?
   The Android build types define properties that Gradle uses when building and packaging of your Android app. A build type defines how a module is built, for example, whether ProGuard is run. A product flavor defines what is built, such as which resources are included in the build. Gradle creates a build variant for every possible combination of your project’s product flavors and builds types. The build type Gradle automatically downloads packages whenever we add any new package for our project. If Gradle is not built properly we get an error in our application.
6. What is intent in Android?
   The intent is connected to either the external world of application or the inner world of application, such as opening a PDF is intent, connect to the web browser, and more.
